安全针头制造技术

一种安全针头(10)，其包含针头座(30)、刺针(40)与安全护盖(50)，刺针(40)插接于针头座(30)的刺针结合部(31)前端，安全护盖(50)组设于该针头座(30)前端，安全护盖(50)的刺针护套(51)结合弹性体(52)设于针头座(30)内，刺针护套(51)套设于刺针(40)外侧，刺针护套(51)后端的导块(512)伸入针头座(30)的外壳部(33)的锁定导槽(333)中，安全针头(10)用于连接一针筒(20)前端，安全护盖(50)的刺针护套(51)与外护壳(53)双重罩设于刺针(40)外侧，外护壳(53)后端抵靠于针头座(30)的外壳部(33)前端限位，使刺针(40)无插出的可能性，并须先扯断外护壳(53)取下，刺针护套(51)缩入针头座(30)中才能注射，注射后，刺针护套(51)能被弹出而套设于刺针(40)外侧，刺针护套(51)的导块(512)沿着锁定导槽(333)移至锁定凹部(337)中锁定，而无法再使用，由此区别该安全针头(10)已使用过。

Safety needle

A safety needle (10), which includes a needle seat (30), a needle (40) and a safety cover (50), and a needle (40) inserted in the front end of the needle combination part (31) of the needle seat (30), and a safety cover (50) set in the front end of the needle seat (30), and a needle sheath (51) of the safety cover (50) in the needle seat (52), and the needle sheath (51)). On the outside of the needle needle (40), the guide block (512) of the rear end of the puncture needle sheath (51) extends into the locking guide slot (333) of the shell part (33) of the needle seat (30), and the safety needle (10) is used to connect the front end of a needle (20), the safety cover (51) and the outer shell (53) are double housed on the outside of the needle (40), and the outer shell (53) back to the outside of the needle seat (30). The front end of the shell (33) is limited to the possibility that the needle (40) is not inserted, and the outer shield (53) must be cut down first, and the needle sheath (51) can be injected into the needle seat (30) to be injected. After the injection, the piercing needle sheath (51) can be ejected and set on the outside of the needle (40), and the guide block (512) of the needle sheath (51) is moved along the locking guide slot (333) to the locking recess (337). The safety pin (10) has been used since it is locked and cannot be used again.
